The MAX4401 features a low-power shutdown mode.
When SHDN goes low, the supply current drops to 20pA
(typ) and the output enters a high-impedance state. Pull
SHDN high to enable the amplifier. Do not leave SHDN
unconnected. Figure 4 shows the shutdown waveform.
The MAX4400–MAX4403 outputs typically settle within
5µs after power-up. Figure 5 shows the output voltage
on power-up and power-down.

Power-Up
The MAX4400–MAX4403 operate from a single +2.5V
to +5.5V power supply. Bypass the power supply with a
0.1µF capacitor to ground.
Good layout techniques optimize performance by
decreasing the amount of stray capacitance at the op
amp’s inputs and outputs. To decrease stray capaci-
tance, minimize trace lengths by placing external com-
ponents close to the op amp’s pins.
